(M20) Am I overthinking/doing too much

Me and this guy have been talking for three months now. We text a lot throughout the day, and have hung out three times now. It’s hard seeing each other while I’m in college but when I’ve come home that’s when we hang out. The last time we hung out I was open with him and said that I don’t want to just be friends, a hookup or just someone on his roster and if that’s what I am then tell me. He said I wasn’t and he’s unsure of himself but still wants to see what the future holds for our relationship and listed activities he wants to do with me. He also said he stopped talking to other guys since he’s met me. And okay this might sound childish but I found out that he’s #1 on some other gay man’s bsf list on Snapchat. Sooo like he’s lying abt talking to other guys right? And this man lives closer to him than me. Idk I hate getting attached, especially for this long, and it just doesn’t work out. And I’m not built for hookup culture or fwb. I probably need to be more mature within my relationships but I feel like I’ve been doing good with him. Other than two times I was drunk and he wasn’t answering me but was active and answering others so I called him out for it. Was I in the wrong for that? I don’t like people being nonchalant and I respect him when he’s busy but why would I be getting ignored? And we’ve communicated about me being drunk at college and he said he was worried I would be drunk and find another guy and flirt with him and he doesn’t want that. I told him I wouldn’t do that because I like him and am a loyal person, and I don’t drink on campus anymore so I let him know. Am I going down the wrong path waiting for him? I haven’t liked someone like this in a long time.
